Cryogenic coolant circulation pump precautions

[Asia Fluid Network News] Low-temperature coolant circulation pump is mainly used in mechanical form of refrigeration cryogenic liquid circulation equipment. Low-temperature coolant circulation pump has to provide low-temperature liquid, low temperature water bath role. Combined with rotary evaporator, vacuum freeze-drying oven, circulating water vacuum pump, magnetic stirrer and other equipment. What should users pay special attention to when using these products? The attention of these issues may have what effect on the user. Low-temperature coolant circulation pump Precautions What are the precautions for using the low-temperature coolant circulation pump? 1, before using the low-temperature coolant circulation pump in the tank should be added to the liquid medium (pure water, alcohol, antifreeze can be), the medium level should not have cooling coil within the tank and lower than the table 20mm is appropriate; , Power: 220V50Hz, the power supply should be greater than the total power of the instrument, the power supply must have a good "grounding" device; 3, to avoid acid-base substances into the tank corrosion coil and the liner. 4, the instrument should be placed in a dry and ventilated place, no obstacles within 300mm around the instrument; 5, often observe the level of the tank surface, when the liquid level is too low, liquid media should be added in time; In addition to the most important points above, Users should also pay attention to when the low temperature coolant circulation pump operating temperature is low, should be careful not to open the cover, hands do not enter the tank, to prevent frostbite; use is completed, all the switches are turned off, cut off the power; liquid outside the loop , The customer should pay special attention to the firmness of the outlet pipe connection and prevent it from falling off so as to avoid liquid leakage. Instruments should be regular cleaning, long time do not have to empty the tank of the media, and wipe clean, keep the work surface and the operation panel clean. Care about these issues is likely to have great significance for the future work and production.
